Abstract
- We consider the isothermal flow through a cylindrical flat chamber, a model of some particular heat exchanger, for which LDV measurements and a numerical simulation have been performed. Experimental results show the establishment of an important vortex zone, the secondary flow extending all along the chamber radius. This observation leads to an expected significant increase of the fluid mixing. Results issued from the numerical simulation appear to be in close agreement with experimental data. Nevertheless, the <f>k</f>–<f>&epsiv;</f> model used here must be improved to obtain a better approach near the vortex centre. To cite this article: S. Petitot et al., C. R.
